FLUID-PRESSURE MOTOR.

Speciflcation of Letters Patent.

Patented Oct. 29, 1907.

Application filed Kpril 24. 1905; Serial No. 313.465- Renewod March 20. 1907- Serial No. 363.451.

o all whom it may concern:

Be it known that I, SPENCER Qris, a'citizen ofthc United States, resi(ling at Chicago, in the county of I pressure generators which may be of any desired type.

In the specific form sho'wn they are indicated as being boilers of the flasher type. These generators are connected to a fluid pressure motor by independent connections a, b and d, the connection a being from the generator (1, the connection b from the generator b and the connection 0 from the generator 0.

d indicates a motor, shown in the drawing as a steam turbine of any well-known construction.

Controlling the admission of steam to the axes of the turbine are the nozzles a 6- and 0', having valves a", b and c -'the nozzles and valves being of any approved type. To these nozzles are attached the connections a, b and c. 1

It will of course be understood that my invention is I not limited to a motor such as shown. For example, I may connect the generators independently to independent cylinders of a reciprocating engine, such cylinders to be attached to the shaft of the engine independently.

By the construction above described I am enabled to supply motive fluid under pressure from any one or from all of the generators; or from any desired combination of the generators, to the motor, thus furnishing motive fluid under different pressures to the IllOtOYtIC Ll'li same time. For example, when it is desired to run the motor with steam from the generator a-h avi ng a pressure say of 250 pounds, this may be done by adinilting strain from the generator through the connection a. and lbo nozzle a Now, if it is desired to admit steam from the generator 5, having say a pressure of 500 pounds, it may be done through the connection b and the nozzle II If it further be desired to admit steam from the gene-later 0, having a pressure say of 750 pounds, it may be done through the connection 0 and the nozzle 1: The pressure, therefore, from each of the generators is effectively utilized. liy c nnecting. the generators, as above doscribcd, I do away with the equalizing drum commonly employed and with reducing valves or throttles. It steam from a high pressure generator is being admitted to the motor, it does not prevent the effective use of steam from a low pressure generator, as will be readily understood.

In the embodiment of my invention shown, I have used flash boilers because, as will be readily appreciated, my invention is of great advantage in boilers of this type, flasher generators being adapted for the economical production of small amounts of steam at high pressures. By connecting a number of such generators independently to the motor, I can'provide for variable pressure in'ihe motor with generators of this type.

I claim: 1

1. In combination with 11 fluid pressure motor, a series of independent generators euch generator being independently directly connected to the motor to supply motive iiuid thereto. substantially as described.

2. In combination with n iiuld pressure motor, a series oi independent generators, the fluid in the generators being ut different pressures each generator being independently directly connected to the motor to supply motive fluid thereto.

2;. in combination with ii iluid pressure motor, a series of generators of the flasher type, ouch generator being independently directly connected to the motor.

4. in combination with :1 fluid pressure turbine, :1 series oi generators cur-ii generator being independently directly connected to the turbine.
